This is the LVPP sigma-profile database for COSMO-based models. It currently contains information for more than 1700 molecules as well as COSMO-SAC parametrizations.
For the COSMO-SAC parametrizations, check the pars folder.
Currently, in this repository we only provide the COSMO apparent surface charges computed either with GAMESS or MOPAC.
You will still need JCOSMO other software to actually compute activity coefficients or other properties with models like COSMO-RS or COSMO-SAC.

The processed database is made available in ZIP files, check the releases. Just download one of the release files, uncompress and look for the molecule you need. JCOSMO can be used to view the 3D apparent surface charge densities.
Currently we have the following releases:
- HF+TZVP using GAMESS
- POA1 using MOPAC
There are different methods to extend the database.
Just create and new issue and describe the molecules you need that are missing. If possible also attach a 3D mol file for each molecule you want added. It can take a while until we process your request.
If you can't wait for us to process your molecules (or if you don't want to) you can can process your own molecules.
Just clone or download this repository and then please check either the GAMESS or the MOPAC folders for instructions on how to process your own molecules.
Our instructions are for Ubuntu Linux 16.04 or superior. They probably should also work on other similar systems.
